O11 Slick at Harbour Drainage Works

RECOMMENDATIONS:

That City staff continue to maintain the oil trapping boom located
at che entrance to the Harbour Drainage Outlet Works, and to monitor the
ditches in the area periodically to see if the source of the oil slick can be
identified.

BACKGROUND AND COMMENTS:

At the Council meeting of February 26, 1990 it was brought to the
attention of the Chairman of the Environmental Protection Committee that an
oil slick had been observed at the entrance to the Harbour Flood Boxes and
Pump Station. Staff has investigated the report and has been unable to
identify the source of the oil. The Broadway Ditch was clear all the way to
Kingsway with no visible signs of oil contamination from any properties
adjacent to the ditch. All recently constructed developments in the area have
been required to install oil interceptors in their drainage systems.

There is an oil soaking boom in place across the inlet channel in
front of the Harbour Pumping Station which will be extended to cover the
entire channel. This boom will prevent the oil from entering the Pitt River,
and it will be maintained at regular intervals to ensure its integrity.
Because a point source of the oil cannot be detected, this would appear to be
the only way to protect the Pitt River from contamination. The ditches in the
area will be monitored periodically to see if the source of the oil can be
identified.
